Question

Your team uses Azure Pipelines with a multi-stage YAML pipeline that runs unit tests and publishes results using the PublishCodeCoverageResults task. Leadership mandates that no pull request may be completed unless the changed code meets an 80% line coverage threshold, and the check must automatically block the PR if coverage falls below that level. What should you implement to enforce this requirement?

Accepted Answer

Add a branch policy build validation on the target branch and configure the pipeline with a code coverage check (e.g., a coverage threshold step that fails the build) so the required status check blocks completion when coverage is below 80%.

Answer

Configure a release gate with an Azure Monitor query that evaluates coverage after deployment to production.

Answer

Enable the built-in 'Coverage' retention policy in project settings and set it to 80 percent.

Answer

Add an environment approval check on the build stage that requires a reviewer to manually verify coverage before the PR merges.
